There are two input voltage ranges. The 72 VDC nominal models accept an input from 36 to 140 VDC and the 110 V nominal versions have a 55 to 176 VDC input. A trim pin allows a +/-10% adjustment for single output models. Using convection cooling the converters have a wide operating temperature range of -40°C to +85°C and a maximum case temperature of 105°C. • 72 & 110 VDC Input for Railway Applications • Single and Dual Outputs • 1500 VAC Basic Isolation • High Power Density • High Efficiency Up to 90% • Remote On/Off • 3 Year Warranty 40 Watts Dimensions: RDC40: 2.00 x 1.60 x 0.4” (50.8 x 40.6 x 10.16 mm) www.xppower.com Models & Ratings Notes Input Voltage Output Voltage Output Current Input Current(1) Maximum Capacitive Load Efficiency Model Number(2) No Load Full Load 36-140 VDC 3.3 V 10.00 A 30 mA 526.82 mA 25000 µF 87.0% RDC4072S3V3 5.0 V 8.00 A 30 mA 617.28 mA 2000 µF 90.0% RDC4072S05 12.0 V 3.35 A 25 mA 641.76 mA 2500 µF 87.0% RDC4072S12 15.0 V 2.65 A 25 mA 627.37 mA 2500 µF 88.0% RDC4072S15 ±12.0 V ±1.65 A 30 mA 632.18 mA ±1600 µF 87.0% RDC4072D12 ±15.0 V ±1.35 A 30 mA 639.20 mA ±1600 µF 88.0% RDC4072D15 55-176 VDC 3.3 V 10.00 A 20 mA 344.83 mA 25000 µF 87.0% RDC40110S3V3 5.0 V 8.00 A 25 mA 408.58 mA 2000 µF 89.0% RDC40110S05 12.0 V 3.35 A 25 mA 420.06 mA 2500 µF 87.0% RDC40110S12 15.0 V 2.65 A 25 mA 410.64 mA 2500 µF 88.0% RDC40110S15 ±12.0 V ±1.65 A 20 mA 413.79 mA ±1600 µF 87.0% RDC40110D12 ±15.0 V ±1.35 A 20 mA 420.78 mA ±1600 µF 87.5% RDC40110D15 1.
